In the production of various kinds of fabrics in textile mills the clothis woven on looms located in a weave-room and the weft or filling-yarnis supplied thereto on bobbins prepared in a separate department such asa winding room. With such previously-used practice the winding ma-'chines must be tended by operatives and the By use of the presentinven-' inated, thus effecting a very considerable saving infloor-space, cost of light and heat, upkeep, etc., besides materiallyreducing labor charges. It will thus be observed that the presentinvention assumes great importance as its use results in manifoldeconomies to reduce the cost of weaving various kinds of fabric on broadlooms.

General organization Referring to the present drawings, Fig. 1illustrates a portion of an automatic loom at the filling-changing end,showing the automaticallyoperated bobbin-winding means, including bobbindonning-and-dofling mechanism, and the various other instrumentalitiesfor furnishing weft or filling-bobbins to the shuttle or shuttles of theloom. Also illustrated in Fig. 1 is a bobbinstripper, so-called, forreceiving spent bobbins ejected from the loom-shuttle, removing theresidue of yarn usually remaining thereon in the bunch or reservewinding, and conveying the stripped or denuded bobbins back to themagazine of the winding means for donning them thereon in connectionwith the rotary winding spindle. One preferred type of such abobbinstripper is illustrated and described in our prior application forUnited States Letters Patent, Serial No. 112,362, filed August 25, 1949.The loom may be of conventional type as regards its general organizationwith its automatic fillingchanging mechanism modified as required forcooperation with the bobbin-winding means; and the automatic windingmeans may be of a type such as shown in United States Letters PatentsNos. 2,257,651 and 2,302,715. The loom may comprise the usualreciprocating lay 2, shuttle 5 received in the box 6 at the end of thelay, the picker-stick 1 for driving the shuttle from this end of theloom, and the various other instrumentalities generally employed inautomatic looms. The automatic filling-changing means for transferringfresh bobbins to the shuttle is described more in detail hereinafter inconnection with the bobbin-winding and furnishing means.

Bobbin-winding means As herein illustrated, the winding mechanism isincorporated in the frame 4 of the loom and located above thefilling-changing mechanism with its driving means enclosed in a housingor casing 8 and driven by an electric motor 9, also enclosed in thecasing. The winding spindle l0 projects from one end of the casing 8 andcarries a recessed driving-center or spindle-cup II for receiving thehead h of the bobbin b as shown in Figs. 4 and 5. The tip end of thebobbin b is likewise supported in the recess of a rotatable center 2 atthe end of a stub-spindle or slidable plunger l3 held in an outboardbearing [5, similar to the tail-stock of a lathe. The outboard bearingi5 is shiftable to retract the outer spindle-center I2 and release awound bobbin for doffing it from the winding spindle [0; theinstrumentalities for effecting the dofling operation being describedmore in detail hereinafter.

Empty bobbin magazine Mounted above the winding means is a magazine 20for containing empty bobbins b, which may be of wood or other materialin conventional shape with an enlarged head it at one end and a barreltapering towards its opposite tip end. Preferably, bobbins of a typesuch as shown in an application for United States Letters Patent SerialNo. 76,365, filed February 14, 1949,

axial alinement with the spindle-centers II and I2 for engagementtherewith. .At this juncture the outboard bearing I5 is slid forwardlytowards the casing 8 to engage the tip end of the bobbin 5 with theouter spindle-center I2 and shift the bobbin axially in the samedirection to carry its head in into engagement with the drivingspindlecenter II. During this operation of donning an empty bobbin thewinding spindle ID is at rest, its rotation having been arrested by thedisengagement of the clutch-means described above, but as an emptybobbin is donned between the spindle-centers the movement of theoutboard bearing to the left will effect reengagement of theclutch-means to restart the rotation of the spindle.

Ya'rn tension-control The filling yarn :11 may be supplied from anysuitable source which is shown in Fig. 1 as a conical package P mountedon a spindle or holder projecting above a shelf 4I upon a column 42supported from the fioor at the end of the loom. The yarn y leadsupwardly from the supply-cone P and feeds through a tension-device 43comprising a plurality of cooperating disks 44 and 45 rotatable aboutvertical spindles 45. From the tension-device 43 the yarn leads througha guideeye .41 and thence is drawn down to deliver through an eye 48 inthe yarn-guide 25 for attachment to the empty bobbin 5. In order thatthe yarn may not be stretched, strained or broken when taken up suddenlyby the initial rotation of the bobbin b, means are provided forrelieving the tension thereon at the start of the winding; such a formof tension-control being shown in United States Letters Patent No.2,236,459 of March 25, 1941, as operated from the winding machine bymagnetic means. In the present form of construction the tension-controlis operated mechanically by means actuated from the rod 40 which rotatesthe arms 23 and 24 for donning the bobbins in connection with thewinding spindle. As shown in Fig. 5, the end of the rod 40 carries asmall beveled pinion 50 meshing with a larger gear 5| on a shaft 52. Thegear 51 carries a pin 49 in its hub projecting upwardly therefrom forengagement with a lug on one arm of a bell-crank lever 53. This arm ofthe lever 53 is connected to a rod 54 slidable in a bearing 55 formed inthe framework above the loom. The upper end of the rod 54 is connectedto a Bowden wire 56 which is slidable in a flexible tube 51 reachingupwardly to the tension-device 43. Referring to the detailed view, Fig.19, the upper end of the Bowden wire 56 is connected to a rockable lever58 which is pivotally mounted on a bracket 59 supported on the mountingfor the tension-disks 44 and 45. A helical spring 80 surrounds the wire56 between a fixed arm 5! depending from the bracket 59 and the end ofthe downwardly-extending arm 62 of the lever 58 and normally tends torestrain the latter against the pull of the wire. The lever 58 has aportion 63 extending alongside the tensiondisks with inclined fingers 64reaching laterally therefrom for engagement under the rims of the uppertension-disks 44. When the Bowden wire 56 is drawn downwardly by theoperation of the lever 53 it acts to rock the lever 58 to raise thefingers 64 and thereby lift the upper tensiondisks 44 free from thelower disks 45 to relieve the tension on the yarn feeding between thedisks. After the bobbin b starts to rotate and winds on a few coils therod 40 is turned in the opposite direction to return the arms 23 and 24to first position. This rotates the. pinion 50 and' turns the gear 5| torelease the pin 49 from the lever 53 so that the tension-control lever58 is rocked by the spring 60 to remove its fingers 64 from under thetension-disks 44. The tensiondisks 44 thus are returned into cooperativerelation with the disks 45 to apply the prescribed amount of tension tothe delivering yarn y.

The tension-control is also operated during each doffing cycle by meanslater described to release the yarn so that the wound bobbin is free todrop into the magazine without being restricted by its trailing endbefore it is severed from the supply yarn. As the yarn y feedsdownwardly from the tension-device 43 it draws across an invertedU-shaped thread-bail III in the nature of a drop-wire. The bail I0 ispivoted to rotate when released by a break in the yarn to actuate thestopping mechanism in a manner as usually provided in winding machines.

Manually-operative starting means To start the rotation of the windingspindle I0 after piecing up a broken yarn the outboard bearing l5 mustbe moved to the left and this may be accomplished manually through themeans of a hand-lever II shown in Fig. 5. The hand-lever II is pivotallymounted in a box-like bearing at the right-hand end of the framework andcarries a rotary spindle I2 projecting downwardly therefrom. The spindleI2 is surrounded by a helical spring I3 held under tension to normallymaintain the lever H in a forward position. On the lower end of thespindle I2 is a cam-piece .14 which is engageable with the end of aslidable pin I5. The end of the pin I5 is adapted to engage the end of astud I6 projecting from the rearward end of theoutboard bearing I5whereby when the hand-lever is pressed rearwardly it will rotate thecam-member I4 to force the pin against the stud and shift the outboardbearing I5 forwardly into operative position. This means for moving theoutboard bearing into operative position can also be employed when thewinding is first started and the bobbin is inserted into place betweenthe spindle-centers; it being unclerstood that the plunger-spindle I3with its center I2 may be forced back sufiiciently against the tensionof the spring 31 as the tip of the bobbin is placed therein to permitthe head of the bobbin to be inserted in the recess in the drivingcenterII.

Referring to Fig. 5, the relief of tension on the yarn as the woundbobbin is dropped into the magazine is accomplished by the shifting ofthe outboard bearing I5 to the right during the doffing cycle. Anelbow-shaped lever TI is pivoted on a screw 18 fastened to the bottom ofthe box-like opening in the framework which encloses the gears 58 and 5Iand the bell-crank lever 53. A pin I9 held in a boss on the side of theoutboard bearing I5, see dotted lines in Fig. 5, is adapted to strikeagainst a depending portion of one arm of the lever 11 to rock thelatter in contraclockwise direction when the bearing I5 is moved towardthe right as viewed in Fig. 5. This causes the opposite horizontal armof the lever TI to engage the lower arm of the bell-crank lever 53,whereby to rock the latter to draw the Bowden wire 55 and operate thelever 58 to lift the upper tension-disks 44 and relieve the tension onthe yarn for starting the winding. It will be understood that the spring60, see Fig. 19, normally tends to rock the tensioncontrol lever 58 torelease the fingers 64 from the tension-disks when the pull on the wire56 is released so that they will apply the prescribed amount oftensionto the yarn. as it feedsto the" bobbin after the winding isstarted;

Yarn-retriever and transfer-tail clip It has been stated that instarting: to. wind on a newly-donned bobbin the yarn is fastenedtheretoby sliding it under the prongs or fingers p on: the ferrule surroundingthe barrel of the bobbin. It has also been. indicated that theyarntrailing. from the dotted bobbin is severed and: its end carriedoutward to. a tensioning drum for holding; it extended from the bobbinwhen; the latter is transferred to the reserve magazine of the loom. Themeans for performing these several functions consists" in a pair ofslidable clips 83 and 84- arranged to travel first in one directionandthenin the: opposite direction in difi'erent parallelcourses belowthe winding bobbin. The clips 83' and 84 are shown in detail in Figs. 14and 1 5 andthe means-tor sliding them horizontal. paths is illustratedin Fig. 9; A; sort of rolling trolley is employed for this purpose, areciprocable bar 85 moved from a leverfit in the casing 8. beingconnected to a carriage 87 onwhich are journaled two pairs ofspur-gears- The lever 86 maybe actuated by a crank-motion in the casingB as shownby dotted lines in Fig. 8 and. indicated generally by thereference character 88. One pair of gears is constituted by apinion 89.connected to a. larger gear 90, arranged with the teeth of the pinionengagin the-teeth on a-fixed rack 91. I The larger gear 9% of the pairhas its teeth in mesh with a rackbar 9-2 which is connected to the upperyarn-clip 83 for sliding, it. The other pair of gears comprises apinion:% arranged with its teeth in mesh with those of a fi xed. rack.91 and. connected to a larger gear 91 meshing with a rack bar 94 whichis fastened.- to the lower clip 83 for sliding it. Through thisarrangement the motion transmitted tothe rod 85 is multiplied to slidethe two rack-bars 92 and $14 with an augmented length of traverse so. asto travel the clips in opposite directions at accelerated rates. ofspeed in the manner and for the purpose as more particularly pointed.-out hereinafter.

Referring to Figs. 14 and 15, the: two clips 83 and- 84: are ofsubstantially the same construction and arrangement but reversed inposition with the reentrant openings between. their jaws facing inopposite directions. As shown. in Fig. 14., the upper clip: 33;.calledthe: retriever, consists. in a rectangular mounting tilt ofU-shape having a fixed jaw Iii-t formed. by one of its depending sidewalls which. is flared outwardly at its end. A movable jaw M2 of similarshape is loosely mounted. on horizontal studs its and HM projectingthrough the sides of. themounting Hill to adapt this jaw to rock: towardthe; fixed jaw Hit. A helical spring 865 coiled around the stud Hi3acts. to force the. movable jaw I02 toward. the fixed jaw wt to clampthe yarnitherebetween as it is entered between the flaring ends of thejaws. A cam-member N16 is sliolably held on the under side of themounting Hit by means of studs It! and} we projecting through sl'ots-Hi9 and M ll: in said member; The slot.

The camememberHi6. slides against. a. plate Ht fase teneolitn. the under side, of themounting. IUD; the forward: end; of this; plate being. beveled on oneside to coact with the edge of the forward finger N2 of the cam niemberit. during cooperation of the flaring ends of. the jaws. ifll" and 5'92.The edges. of; the beveled end. of-the plate H8. and the finger t it onthe camem'emher' [t6 are sharpened; as: regards the construction or the.clip; 84, for cooperation ire manner of knives or shears to out the.length at yarn held between the jaws lfirl aslater-explained; On theother hand, in. the arrangement. 01?; the. clip. 83 the cammember lilfioverlie the upper face of. the plate i lti with a clearance thesehetweenso. thatv these parts. do not. act. as shears. The clip 83: carries ablade-like element. H15 fastened; to. the inner face of. the depending.side of the mounting I'M and formed at its forward. end: with an arcuateextension M13 employed for a purpose later ex.-' plained.

As; before noted; thec1ip=34 is. of substantially the same ccnstrucia'onand; arrangement as that of the clip es; and corresponding. parts are.referred to in the drawings by the same reference" characters. As shown;Figs. 15 and; t6, the clip 8% is provided with means. for opening itsjaws HM and let!- without slidingithecaimmernber the. For this purpose acylindrical cam E28 ismounted to rotate-on; the. stud Hit. The endv ofthe cam I23 is ferment helicallyi sothat as it is. turned. on the studHit it will act against the rearward end of the movable. jaw tea to rockthe latter this end of the jaw being. formed at an angle" to: its mainportion to provide. for the rocking action. A pin 52}. projects.radially from the cam the for rotating it to open the jaws Ital! and Weof the clip M .at the end of its travel whereby to rep. lease the yarntheretrom after: it is. clamped: above the rotary tensioning; drumdescribed later. The pin t2! strikes against a abutment E 216, see Fig;5', which acts to: rotate'the cam; IfZ ll to open the: jaws of; the. cliat at the end or its travell.

Referring to:- Figs'. "7;,.12.'and.13,.thetwo clips 83 and 8d areoperated. during the rioting or the wound bobb-inandi the donning-0t anempty bobbin in. the m-anner'as. neat explained. The clips slide ingrooves F22. E23 in. thebase of the frameworkv of the wmding. mechanism,being moved toward and away from each other by the travel: of therolling; carriage 8:?! under the operation' of the crank-motion 33previously men.-' tioned. As th-eelips 8ft andtt meetam'd pass'e'achother they continue their motion to engage the yarn trailing from thedefied. bobbin and: cause it to enter between their'jaws. The: yarniiisen tered between the: flaring ends of the jaws it"! and. me.- which;are: them closed; together to time and hold theyarn'; Tn'eacl'os'i-ngofqthe' jaws of the twoclips is; effiect'ed by; sliding the: cam-membersuse to cause. them tot release themovable jaw I B2 on each clip andpermit the spring L- to force it against the fiir'edljaw. Hi If. Thissliding motion or the camemembers tilt is: caused by their en gagementwith; beveled; endsof a; pair at rails I24- and I 2e5 e'xtemdinghorizontally alongthe base of the framework, see Figs. 51,. 1-4.- and Asshown. in Figs. 14. and. 1i5 ,.t1te cam-members we have rounded-sideportions. BM adjacent. their forward. endswhiclr engage. against thebeveled ends of the rails I24 and I to slide the members rearwardly onthe clips 63 and 84. As the cammembers I06 are slid in this manner theyare rocked laterally to release the movable jaws I02 of the clips forclamping action by the springs I03. As the clips 83 and 34 continuetheir travel in opposite directions toward their stations the roundedside portions III of the cam-members I06 ride along the rails I24 andI25 with the movable jaws I02 released thereby and acting to clamp theyarn y against the fixed jaws IOI.

Referring to Figs. 12 and 13, as the clips pass each other thecam-member I06 on the lower clip 84 is slid by its contact with the endof the rail I25 to not only cause the closing of the jaws, but also tomove the shearing edge of the cammember across that of the blade II6 tosever the length of yarn y leading between the clips. In this way theyarn trailing from the doffed bobbin is severed from the end in theyarn-guide 25 so that it may be carried to the tensioning drum in themanner as later explained.

The retriever-clip 83 which has clamped the end of the yarn y leadingdown from the yarnguide 25 continues its travel to the left, as viewedin Figs. 12 and 13, and besides retrieving this end for attaching it toa newly donned bobbin b, it acts to return the yarn-guide 25 to initialwinding position adjacent the head of the bobbin. The clip 83 isconnected to slide the yarn-guide 25 by latching means shown in Fig. 13.The latching means may comprise a slidable bar I mounted on alaterally-extending rest or plate I3I which is fastened to the rearwardside of the clip mounting I00. The slide-bar I30 is formed withlongitudinally-extending slots I32 and I33 through which engage pins I34and I35 projecting upwardly from the plate I3I. Pivoted on the pin I34above the slide-bar I30 is a pawl-like latch I36 formed with a shoulderI3l' engageable with the edge of the vertical arm of the yarn-guide 25,see Fig. 12, to cause it to transmit the motion of the clip 83 to theguide for sliding it. The latch I36 carries a depending pin I38 at itsend engaging in the slot I32 of the slide-bar I30 and adapted to slidein an offset, inclined cam-portion I40 of the slot to rock the latch toengage its shoulder I31 with the yarn-guide 25. A screw I4I, see Fig.13, adjustable through an upstanding lug I42 on the right-hand end ofthe slide-bar I30 is adapted to strike against an abutment I44 formed bya, vertical shoulder of the framework, see Fig. 5, when the clip 83reaches the end of its travel toward the right. When this contact takesplace the slide-bar I30 will be slid to the left to rock the latch I36and engage it with the yarn-guide 25 in the manner indicated in Fig. 12.Similar means are provided at the left-hand end of the slide-bar I30 forsliding it in the opposite direction to release the latch I36 from theyarn-guide 25. This means ma comprise a screw I45 adjustable in anupstanding lug I46 on the slidebar I30, see Fig. 12, the head of whichis adapted to strike against the end wall of the casing 8 to shift theslide-bar to the right and release the latch I36 as shown in Fig. 13.

Referring to Figs. 5 and 13, the travel of the retriever-clip 83 to theleft or toward the casing 8 also performs certain other functions asnext explained. Beneath the head end of the bobbin is a loop-shaped wirebail I50 having one end formed as a pivot-stem I5I rotatable in abearing in the base of the framework, see Fig. 5. A helical spring I52surrounding the pivot-stem I5I of the bail I50 normally maintains itrocked inwardly beneath the bobbin b. When, however, the yarn-guide 25is returned to initial winding position by the travel of the clip 83 theclip acts to swing the bail I50 outwardly into the position illustratedin the plan view, Fig. 13. This swinging motion of the clip is effectedby the arcuate end portion IIS of the member II! with one branch of thebail I50. The purpose of this action is to assist in carrying the lengthof yarn 1 leading from the thread-guide 25 down to the clip 83 in underthe prongs on the ferrule 1 carried by the bobbin 13, see Fig. 5. Theyarn draws down to the clip 83 in back'of the bobbin b as viewed in Fig.5 and it is desirable that it be wrapped partly therearound as it slidesalong the barrel of the bobbin so that it will invariably be engagedunder the fingers p on the ferrule I.

It has been stated that at the start of the winding a bunch containing afew coils of reserve yarn is wound on the bobbin b adjacent its head hwith a shorter traverse than that imparted to the yarn by the yarn-guide25. For this purpose an element I60, called a bunchbuilder, is providedfor holding the yarn to restrict its traverse by the guide 25. Thebunchbuilding element I60 may take the form of a flat metal bladepivoted on a pin I6! and having a pin-and-slot connection with means forprojecting it into position to engage the length of yarn between theguide 25 and the bobbin. The blade I60 is actuated by means not hereinshown in detail but described in the continuing application referred topreviously. Suffice it to explain, that as the yarn is carried back toengage it under the prongs p on the ferrule f it will ride across theedge of the bunch-building blade I60 so that when the blade is swungforward it will be engaged therewith to hold it from being traversed tothe full extent by the yarn-guide 25. The blade I60 also cooperates withthe bail I50 as indicated in Fig. 5 to cause the yarn leading down fromthe guide 25 to be wrapped partly around the barrel of the bobbin toinsure its engagement under the prongs p on the ferrule I.

As the retriever-clip 83 reaches the end of its travel after attachingthe yarn to the bobbin 5 the end of the yarn is released therefrom,being pulled out from the jaws of the clip as the bobbin starts torotate, it being understood that the jaws IN and I02 remain closed bythe spring I05. When the clip 83 is again traveled to the right,however, at the start of winding the next bobbin the rounded side II Iof the cam-member I06 will ride off from the beveled end of the railI24, see Fig. 14, and the opposite end of the cam-member will makecontact with the end of an adjustable stud I25 held in a lug I27 on adepending portion of the tail-stock I5 to slide the cam-member to openthe jaws of the clip.

Trans fer-tail tensioning drum Referring to Figs. 9 to 11, 16 and 17,the tensioning drum I10 which holds the end of the trailing yarn fromthe doffed bobbin is rotatably mounted in a recess or compartment I'IIof the framework below the winding mechanism. The drum I10 is in theform of a sheet-metal cylinder supported by circular disks I72 and I73at top and bottom of its interior. Projecting from the top of thecylinder I10 are a. series of spaced teeth "5 inclined outwardly in theform of a 13 comb which acts to catch the yarn carried to the drum bythe clip 84,see Figs. 16 and 17.

Yarn-detention gripper In order to prevent the end of the yarn y frompulling out or becoming detached from the teeth [T5, means are providedfor gripping it at a point within the confines of the comb as shown inFigs. 16, l? and 18. This detention means consists of a flap-likegripper llii having ears at its upper end pivoted on a pin i'li held ina bearing member H8 fastened to the framework at 579. A helical springiii!) coiled around the pin ill has one end held fast and its oppositeend It! engaged against the gripper, see Fig. 18, to normally rock itdownwardly. The lower edge of the gripper Hi; is adapted to engageagainst a resilient pad E82, constructed of spongewubber or the like,across the top of which the yarn is drawn as it is carried toward theright by the clip 84, see Fig. 5. The yarn y is drawn under the loweredge of the gripper I'M; as the latter is swung upwardly during thetravel of the clip 84 toward the right as shown in Fig. 16. Pivoted onthe pin ill in the bearing I18 is a depending plate 583 with which theclip 84 first makes contact to swing it against th gripper H6 and liftthe latter for the passage of the clip thereunder. As the clip 83approaches the end of its travel it passes beyond the gripper H andreleases it to swing downwardly under the force of the spring its topinch the yarn against the top of the pad 982 and resist its releasefrom the drum ill). During the rotation of the drum lit the fingers N5of the comb will carry the yarn onto the periphery of the drum under thebail M18, as shown in Fig. 10, to hold it under tension. The drum Ellipreferably is covered with a roughened material such as fabric toprevent the yarn from slipping thereon. Means are provided for releasingthe end of the transfer-tail from the clip 8 after the latter hasconnected the yarn to the drum H0. For this purpose an abutment lit atthe right-hand end of the framework, see Fig. 5, has aforwardly-projecting finger positioned to engage the pin ill and rotatethe cylindrical cam lit to cause it to rock the movable jaw 102 of theclip 8 away from the fixed jaw llll in the manner previously explained.When the clip 85 is returned in the opposite direction for positioningit to pick up the transfer-tail from the next (lofted bobbin it mustpass the gripper H6 and this is provided for by an opening I8 3 in theside of the gripper, see Fig. 18. During the further travel of the clip84 to the left it strikes against the suspended plate i331 as indicatedin Fig. 18 to rock the latter outwardly and pass thereunder. Means areprovided for releasing the cylindrical cam lEB from the movable jaw M32as the clip moves to the left toward its station. For this purpose anabutment member ltl', see Fig. 5, is adjustably mounted on the front ofthe framework by means of a screw i228 engaging through a slot in saidmember.v The member 12? has a right-angular portion disposed to adapt itto strike against the end of the cam-member iilb on the clip 84 to slidethe latter forwardly. The abutment member I27 also has a finger i252projecting forwardly from its end in position to strike against the pinhit to rotate the cam lit for releasing it from the movable jaw Hi2. Inthis way the parts of the clip it are reset with its jaws open forengaging the yarn at the next forward travel of the clip.v

Transfer-tail tensiomng drum enclosure As the drum 110 is rotated a bailI98, see Fig. 10, acts to frictionally hold the end of the.transfer-tail against the drum to tension the yarn as it is drawndownwardly therealong during the descent of the bobbin in the reservemagazine. It will be understood that as the bobbins descend in thereserve magazine they drawthe transfertails leading therefrom downwardlyalong the drum l ill so that upon the release of each bobbin from themagazine its respective transfer-tail is disengaged from the drum toadapt it to be caught and held for threading in the eye of the shuttleas later explained. The drum H0 is enclosed in a two-part cylindricalcasing 39 comprising a rearward stationary section 1% fastened to a wallof the framework by screws lbl, see Fig. 10. Attached to this part We ofthe casing [89 is a tubular bearing 192 enclosing a pin 193, see Fig. 9,on which is hinged the forward section [$5. The section (Q5 is adaptedto swing outwardly to open the casing I83 for inspection of the drumI10. A spring, not herein shown, or other suitable means may be providedfor holding the section I of the casing !89 closed. The hinged section1% of the casing its has bearing lugs I96, see Fig. 10, at top andbottom for rotatably mounting the roller-bail I98 in contactwith theperiphery of the drum to press the yarn thereagainst.

Drum-rotating means The drum H9 is rotated by ratchet-mechanism locatedtherebelow and normally actuated from the reciprocation of the loom-lay,see Figs. 10 and 11. The drum I16 is mounted for rotation on a verticalstud-shaft 200 journaled in a hearing in the base 2b! of the compartmentl'li of the framework of the winding means. The studshaft 208 projectsthrough a bore in the lower disk N3 of the drum H0 and the disk H2 atthe upper end of the drum is rotatable on a ShQ'lll-r dered stud 202projecting downwardly from a portion of the framework. Fastened againsta boss or hub 2&3 on the under side of the lower disk H3 is aratchet-disk 2% formed with relatively fine teeth on its periphery. Theratchetdisk 284. is rotatable on abushing enclosing a shouldered portionof the stud-shaft 2&0 and is secured rotatively with the disk life ofthe drum by means of two pins 265 passing therethrongh. A pawl 2M3pivoted to a member 269 which is fast on the stud-shaft lillil isresiliently held in engagement with the teeth on the ratchet-disk 264 bymeans of a leaf-spring 2H1 fastened to the member 289 at 2H. Mountedfast on the lower end of the stud-shaft 268 is a triangularshaped arm2H2 carrying apin H3 at its pointed end to which is connected at heiicalspring 2M anchored to a pin 215 fast in the base iiiiland projectingdownwardly therefrom. The triangular arm 2!!! has a laterally-projectingpointed toe 2l8 at the opposite end from that connected to the spring2M. One edge of the toe 256 is adapted for engagement by a roller 2% onan oscillatable lever 22! which is pivoted on a pin 222 projecting belowthe base 281, see Fig. 11. The 'arcuately-shaped edge of the other armof the lever 22! is positioned for engagement by a hunter 2'23 fastenedto the top of the lay 2 of the loom. Through this arrangement theforward motion of the lay 2 causes the-hunter 223 to strike the lever22! and rock it on its pivot 222 to engage its roller 229 with the toe216 and rock the triangular arm 212., As before, noted,

the arm 212 is fast with the stud-shaft 200 and thereby causes thepawl-carrying member 209 to be rotated therewith to retract the pawl 208rearwardly along the teeth of the ratchet-disk 204. Thus, when thebunter 223 recedes with the rearward stroke of the lay 2 the spring 214will rotate the member 212 and advance the pawl 208 to rotate theratchet-disk 204 and with it the drum 1'10 which turns incontra-clockwise direction as viewed in Fig. 10. This rotation isintermittent and continuous during the operation of the loom as effectedby the reciprocation of the lay 2, the drum 1'10 being turned at arelatively slow speed since the pawl 208 is retracted only a few teethat a time. To prevent reverse rotation of the drum 1'10 a brake-shoe225, shown in Fig. 10, as pivoted on a stud 225, has an eccentric faceengageable with the interior of the drum cylinder. A leaf-spring 221,shown in Fig. 10, tends to rock the brake-shoe 225 on its pivot so thatnormally it has substantially no braking effect against the interior ofthe drum cylinder when the latter is turned in the prescribed directionby the ratchet-means. However, any tendency for the drum 1'10 to turn inthe opposite direction will cause the brake-shoe 225 to dog against itsinterior to resist such rotation.

Means for accelerating drum-rotation It has been found of advantage toinitially turn the drum 1'10 to a greater extent for insuring theattachment of the end of the transfer-tail thereto as the wound bobbinis held momentarily at the top of the reserve magazine. For this purposea rockable lever 230 is pivoted at its upper end to a portion of theframework, see Figs. 8 and 9, to adapt its lower end to oscillate ahorizontal lever 231 for actuating the ratchet-means described above.The lever 231 is pivoted on the stud shaft 200 below the base 201 asshown in Figs. and 11. The lever 231 carries a stud 232 projectingupwardly from its outer end with a convex-sided roller 233 journaledthereon and adapted to be engaged by the lower end of the lever 230. Oneside of the lever 231 is engageable with a lug 234 projecting upwardlyfrom the triangular arm 212, see Fig. 9, whereby the rocking motion ofthe former will turn the latter to withdraw the pawl 208 a considerabledistance rearwardly along the toothed periphery of the ratchet-disk 204.

The lever 230 is released by its actuating means at the end of themotion of the lever to the left as viewed in Fig. 9, whereupon a spring22:? connected at its lower end and anchored at 220 swings the lever inthe opposite direction or toward the right. This latter movement of thelever 230 will release the lever 231 and allow the spring 214 to rotatethe member 212 for advancing the pawl 208 to rotate the ratchet-disk204. This action turns the ratchet-disk at a faster rate for rotatingthe drum 1'10 more rapidly to quickly draw the end of the yarn in thetransfertail between the roller-bail 193 and the surface of the drum. Insome instances it may be necessary to rotate the drum manually to windon the end of a transfer-tail from a bobbin placed in the magazine andthis may be accomplished by means of a finger-lever 235 shown in Fig. 10as pivoted at 236 with its forward hooked end engaged with the roller220 on the lever 221 which is operated by the hunter 223 on the lay ofthe loom.

The lever 230 is swung to the left as viewed in Fig. 9 by the travelingmotion of the carriage 81 as it operates to traverse the'clips 83 and 84for the purpose previously explained. For this purpose the carriage 8'1has a projecting stud 240 at its end adapted to strike against the endof a slidahle rod 241 carrying a collar 242 fastened thereto. The collar242 is adapted to engage the edge of the lever 230 to rock the lattertoward the left as viewed in Fig. 9 to stretch and load the spring 228.When the carriage 8Z reverses its motion to travel back in the oppositedirection the lever 230 is released to swing toward the right andoperate the ratchet-means in the manner as explained above. As shown inFig. 9, the lever 230 is connected by an angular link 243 to a bellcranklever 245 pivoted in a casing 240. The bellcrank lever 245 is rocked bythe lever 230 for actuating detention means for controlling the entranceof doffed bobbins into the reservemagazine at the opposite side of thecasing 248.

Reserve-magazine for wound bobbins Referring to Figs. 2, 3, 5, 6 and '7,the reservemagazine for wound bobbins is similar in general to theconstruction used in conventional automatic looms. The present inventioncontemplates certain improvements for controlling the entrance of eachbobbin into the reserve-magazine to detain it on a rest or shelf for aninterval while its transfer-tail is being held and tensioned by thetensiomng drum 1'10. The control means further provides for arrestingthe operation of the winding means when the magazine becomes filled withbobbins. As shown more particularly in Figs. 6 and 7, the reservemagazine, indicated generally by the reference character 250, isprovided at the top with a hinged rest or shelf 251 which sustains eachbobbin for an instant while its transfer-tail is held by the gripper1'16 above the drum ll 0 and attached thereto by the acceleratedrotation of the latter. The shelf 251 is hinged to the vertical wall ofthe casing 246, previously referred to, to adapt it to swing downwardlyto release the bobbin and allow it to drop down in the magazine 250. Thewound bobbins B are thus supplied to the reserve magazine 250 inoverlying relationship at the rear of the usual filling fork with thelowermost bobbin in position to be transferred to the shuttle by thetransfer-hammer 252 shown in Fig. 2.

Bobbin-detaining means The bobbin-detention shelf 251 is maintainedraised in horizontal position by means of a lever 253 pivotallysupported on a shaft 254 within the casing 246 and formed with a curvedfinger 255 projecting through an opening in the forward wall of thecasing with its end engaging the under side of the shelf, see Fig. '7.The lever 253 is held in the position shown in Fig. '7 with the shelf251 raised by means of a spring 249 on its shaft 254, see Fig. 9. Aftera relatively short interval the doifed bobbin B is released from theshelf 251 by the action of the mechanism contained in the casing 246,see Fig. 9, and previously referred to. The three-armed bell-crank lever245, previously mentioned, has one of its arms 256 carrying a pin 25]engageable through a slot 258 in a vertical link 259. The upper end ofthe link 259 is pivotally connected to an arm 260 reaching outwardlyfrom the lever 253 which supports the shelf 251. When thedrum-accelerating lever 230 is swung to the left by the travel of thecarriage 8'1 the connecting link 243 will rock the bell-crank lever 245to cause its arm 256 to raise the vertical link 259 and thereby rock thelever 253 to withdraw its curved finger 255 from under the shelf 251.
